Quick Q for the Guru's out there.
If I have a CME chassis that is maxed out with the number of ephones it can have (52 on a 2821 for example) and I needed to add more phones, couldn't i just add another Chassis with a different Extension range and have dial peers pointing to each other?
or am I stuck upgrading the chassis to a much larger (read more expensive) system?
In short yes without upgrading the chassis. If using physical IP phones you'd have to manually set your TFTP server. If using softphones you have to set TFTP server anyway.
